Abstract: Abstract: With the rapid development of electronic technology, LED electronic display screen has been widely used in various fields. LED display screen is a non-linear electrical equipment, which will generate harmonic current and cause harmonic pollution to power supply and distribution grid when used, and will cause fire in serious cases. Through the test and verification of LED display screen system in large-scale event site, this paper reveals the mechanism of fire, and puts forward targeted prevention and control measures and emergency disposal methods.
